IMPPLCVEMENT Il\l WATER-HEATERS FOR STEAM-BOILERS.

Specification forming part of Letters Patent No.. 42,2113, dated April 5, 1864.

To all whom it may concern:

Be it known that I, HoRATIo N. WA'rnRs, of the city and county of Hartford, in the State of Connecticut, have invented a new and improved mode of preventing sediment in steanrboilers by superheating the water behaust steam; and I do hereby' decla-re the following to be a full and exact description there of, reference being had to the accompanying drawings, and to thclctters ot reference marked thereon.

Figure lis a side elevation ot" a steamtight tank or reservoir; Fig. 2, a vertical longitudinal section of the same.

A represents the tank; B, feed-pipe for cold water, with a chamber, (cone-shaped and perforated with small holes,) C, at the end of it; D and B, exhaust-pipes; F, feed-pipe to boiler; G, the ordinary water-line. The arrows H H J J show the course of the exhauststeam and Water to and from the tank A.

The nature of my invention consists in heating to or above the ^boiling-point the water for the boiler in another vessel by means of the exhaust-steam, by bringing' it in contact therewith in small quantities or jets and thereby depriving` it of its impurities before entering the boiler.

' To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct a steanrtight reservoir or tank in any convenient form and capacity for the size of the boiler-say, six by two feet for one hundred horse-power, as represented in Figs. l and 2 by A in the accompanying drawings, into which 1 bring the cold water through the pipe B and perforated cone-shaped chamber C; when it comes in contact with the eX- haust-steam from the pipe D, situated immediately over it, and absorbsjall the heat, thereby bringing it-to the boiling point, at which point all extraneous matters held in the water are deposited at the bottom, where they remain, as the pipe F, heilig placed some six inchesahove the bottom ot' the tank A, conveys the pure hot water to the boiler, while the exhaust-pipe E carries ott' the superfluous steam to the chimney or to "the building for heating purposes.

H H J J represent the course of the steam and water; G, the water-tine.

The tank A may have a man-hole or handhole for the convenience of cleaning from time to time, as may be necessary. The tank is placed in any position or locality most convenient to the boiler it is to supply.

The perforated chamber C is made oi' copper, about six inches in height and tive inches at the base, cone-shaped, with numerous small holes sut'ticient to deliver the necessary water to supply the boiler, the whole arranged substantially as within described; and I do not claim merely the heatingl ot' the water for the prevention of sediment, as that has been already accomplished.

I am aware of the plan of heating the water in another tank hy means of the exhauststeam, but as the steam only comes in contact with the surface of the water the operation is slow and il'ieii'ective, producing a temperature of only about 1800, while by my process it is brought to or above the boiling-point, 2120.

What I claim as my invention, and desire to secure by Letters Patent, is-

The arrangement ofthe tank A with the exhaustpipes E and D, and the distribution of the water through the cone-shaped attach- -nient G, in juxtaposition to the exhaust-pipe D.
